G'day, This may not be the best forum for 8051 assembler help. Try a site such as 8052.com; they are using it all the time. However, to answer your question: you would need to use a conditional jump instruction, the format of which depends on where the compared bytes are. For instance, the CJNE mnenomic has 4 forms depending on where the bytes are placed. It compares the two bytes and jumps to a new address relative to the programme counter. It then clears the carry flag if one is greater than the other. Your routine would then have to test this bit and then implement an absolute jump. Hope that helps. Elric
